Strut bar is the bar located in the engine bay; look inside for the two front strut mounts and the bar is placed to bridge these mounts.
The major difference in handling is the sway bar (the rear sway bar in particular). This is the bar that connects the sway bar links together near the struts. Camrys already come with stock sway bars, but aftermarket ones are usually thicker and made of better material.
The strut bar and the sway bars make significant improvement if the car is lowered. If the car isn't lowered, these bars won't help at all.
My 2 cents.
